RESUMEN
BACKGROUND: Anti-TNF therapy represented a landmark in medical treatment of ulcerative colitis (UC). There is lack of data on the efficacy and safety of these agents in Brazilian patients. The present study aimed to analyze rates of clinical and endoscopic remission comparatively, between adalimumab (ADA) and infliximab (IFX), in Brazilian patients with UC, and evaluate factors associated with clinical and endoscopic remission after 1 year of treatment. METHODS: A national retrospective multicenter study (24 centers) was performed including patients with UC treated with anti-TNF therapy. Outcomes as clinical response and remission, endoscopic remission and secondary loss of response were measured in different time points of the follow-up. Baseline predictive factors of clinical and endoscopic remission at week 52 were evaluated using logistic regression model. Indirect comparisons among groups (ADA and IFX) were performed using Student's t, Pearson χ2 or Fisher's exact test when appropriated, and Kaplan Meier analysis. RESULTS: Overall, 393 patients were included (ADA, n = 111; IFX, n = 282). The mean age was 41.86 ± 13.60 years, 61.58% were female, most patients had extensive colitis (62.40%) and 19.39% had previous exposure to a biological agent. Overall, clinical remission rate was 66.78%, 71.62% and 82.82% at weeks 8, 26 and 52, respectively. Remission rates were higher in the IFX group at weeks 26 (75.12% vs. 62.65%, p < 0.0001) and 52 (65.24% vs. 51.35%, p < 0.0001) when compared to ADA. According to Kaplan-Meier survival curve loss of response was less frequent in the Infliximab compared to Adalimumab group (p = 0.001). Overall, endoscopic remission was observed in 50% of patients at week 26 and in 65.98% at week 52, with no difference between the groups (p = 0.114). Colectomy was performed in 23 patients (5.99%). Age, non-prior exposure to biological therapy, use of IFX and endoscopic remission at week 26 were associated with clinical remission after 52 weeks. Variables associated with endoscopic remission were non-prior exposure to biological therapy, and clinical and endoscopic remission at week 26. CONCLUSIONS: IFX was associated with higher rates of clinical remission after 1 year in comparison to ADA. Non-prior exposure to biological therapy and early response to anti-TNF treatment were associated with higher rates of clinical and endoscopic remission.

BACKGROUND: The IBD National Patient Registry is an initiative of the GEDIIB (Brazilian Study Group of Inflammatory Bowel Disease) who aims to survey the epidemiological profile of IBD patients through the creation of a centralized registry with data on patients monitored in public and private health services which will allow the planning of actions by the GEDIIB to facilitate the diagnosis and access to treatment of IBD, enabling the implementation of actions of the GEDIIB and the partnership with government agencies to improve care and, consequently, the quality of life of patients with IBD. This study aims to show the results of the IBD National Patient Registry. METHODS: A cohort study was performed. Data were collected from July 2020 to August 2021. Data were obtained from medical records and/or from patients during the regular follow-up visit and stored in pre-established records for further analysis. Only patients with an established diagnosis of CD and UC were included. The study was approved by the local ethical committees and all patients signed the consent form. RESULTS: In total, 797 patients were included, 60% with UC and 40% with CD; 52.9% from University Hospitals. The mean age was 44.75 ± 16.11 (12 - 92y), 59.9% female, 59.3% married, 76.4% Caucasian, 85.1% non-smokers, 30.5% completed higher education, 14.9% presented familial history of IBD. The age of onset of symptoms ranged from 3 - 79 years (32.94 ± 14.22) and 33.2% presented diarrhea as an initial manifestation. The age of diagnosis ranged from 4 - 81 years (35.07 ± 14.60) and the time from symptoms to diagnosis ranged from 1 to 2 years. The Montreal classification of CD patients were A1: 6.3%, A2: 59.9%, A3: 33.8%; L1: 38%, L2: 16.7%, L3: 43.9%, B1: 51.5%, B2: 27.8%, B3: 7.8%; perianal 12.8%. In UC, 47.8% presented pancolitis, 30.3% left-sided and 21.8% distal colitis. EIMs were present in 45.7% of patients, the most frequent being rheumatological 21.8%. Comorbidities were present in 72%, the most frequent were high blood pressure (15.3%) and diabetes (6.3%); 50% were with BMI > 25 Kg/m2. Most of the patients were in use of medical therapy (95.5%), of which 81.3% salicylate, 70.3% biological therapy, 49% immunosuppressor, 25.6% corticosteroid and 1.2% tofacitinib. Regarding biological therapy, the following medications were used: infliximab 47.6%, adalimumab 28.4%, vedolizumab 9.5%, ustekinumab 7.5%, certolizumab 2.2% and golimumab 1.3%. Eleven women used the medication during pregnancy. IBD surgery-related was performed in 69.7%, 77.2% abdominal and 22.8% perianal. Almost 30% performed more than one surgery. In 62% of patients, at least one complication was reported; most of them were infective disorders, demanding prolonged hospitalizations. CONCLUSION: To date, there is no IBD epidemiologic study covering the entire Brazilian territory. The results found with the registry will be fundamental to show the epidemiology of a country with continental dimensions such as Brazil. The greater the number of researchers included and from different regions of the country, the greater the representativeness of the data and may even help direct government actions on behalf of IBD patients.
RESUMEN
BACKGROUND AND AIM: One of the most impacted regions by the pandemic globally, Latin America is facing socioeconomic and health-care challenges that can potentially affect disease outcomes. Recent data suggest that inflammatory bowel disease (IBD) patients do not have an increased risk of the development of COVID-19 complications. However, the impact of COVID-19 on IBD patients living in least developed areas remains to be fully elucidated. This study aims to describe the outcomes of IBD patients diagnosed with COVID-19 in countries from Latin America based on data from the SECURE-IBD registry. METHODS: Patients from Latin America enrolled in the SECURE-IBD registry were included. Descriptive analyses were used to summarize clinical and sociodemographic characteristics. The studied outcomes were (i) a composite of need for intensive care unit admission, ventilator use, and/or death (primary outcome) and (ii) a composite of any hospitalization and/or death (secondary outcome). Multivariable regression was used to identify risk factors of severe COVID-19. RESULTS: During the study period, 230 cases (Crohn's disease: n = 115, ulcerative colitis: n = 114, IBD-unclassified [IBD-U]: n = 1) were reported to the SECURE-IBD database from 13 different countries. Primary outcome was observed in 17 (7.4%) patients, and the case fatality rate was 1.7%. In the adjusted multivariable model, the use of systemic corticosteroids (odds ratio [OR] 10.97; 95% confidence interval [CI]: 3.44-34.99) was significantly associated with the primary outcome. Older age (OR 1.03; 95% CI: 1.00-1.05), systemic corticosteroids (OR 9.33; 95% CI: 3.84-22.63), and the concomitant presence of one (OR 2.14; 95% CI: 0.89-5.15) or two (OR 10.67; 95% CI: 1.74-65.72) comorbidities were associated with the outcome of hospitalization or death. CONCLUSION: Inflammatory bowel disease patients with COVID-19 in Latin America appear to have similar outcomes to the overall global data. Risk factors of severe COVID-19 are similar to prior reports.

PURPOSE OF REVIEW: Epidemiological studies of inflammatory bowel disease (IBD) in newly industrialized countries are limited, due to a lack of medical surveillance systems and reliable and unified registries and databases. In Brazil, reliable data on the incidence and prevalence of Crohn's disease and ulcerative colitis is scarce. The objective of the present review is to describe in detail the available data on the incidence and prevalence of Crohn's disease and ulcerative colitis in Brazil. RECENT FINDINGS: The authors identified the single four population-based studies which refer to incidence and prevalence of IBD in the country (two from São Paulo, one from Espírito Santo and one from the state of Piauí). These studies demonstrate a remarkable growth in the incidence and estimated prevalence of IBD in Brazil, with higher number of cases in more developed regions. SUMMARY: The increase in incidence over time and the higher current prevalence are indicative of a historical progression in relation to the number of IBD patients in our country, similar to what was observed in countries from Asia and approximating those of the northern hemisphere. Epidemiological studies with more accurate methodology are needed in Brazil.

BACKGROUND: The most efficient way to prevent complications from inflammatory bowel disease (IBD) is to provide patients with optimized care. Nonetheless, in Brazil, there is no validated methodology for evaluating health services recognized as comprehensive care units (CCU), making it difficult to assess the quality of care provided. OBJECTIVE: To understand the current scenario, map the distribution of centers and identify strengths and weaknesses, considering local and regional characteristics. METHODS: The study was carried out in three phases. Initially, the Brazilian Organization for Crohn's disease and colitis (GEDIIB) developed 22 questions to characterize CCU in Brazil. In the second phase, all GEDIIB members were invited to respond to the survey with the 11 questions considered most relevant. In the last phase, an interim analysis of the results was performed, using the IBM SPSS Statistics v 29.0.1.0 software. Descriptive statistics were used to characterize the center's profile. The chi-square test was used to compare categorical variables. RESULTS: There were 53 responses from public centers (11 excluded). Most centers were concentrated in the Southeastern (n=22/52.4%) and only 1 (2.4%) in the Northern region of Brazil. Thirty-nine centers (92.9%) perform endoscopic procedures, but only 9 (21.4%) have access to enteroscopy and/or small bowel capsule endoscopy. Thirty-three centers (78.6%) offer infusion therapy locally, 26 (61.9%) maintain IBD patient records, 13 (31.0%) reported having an IBD nurse, 34 (81.0%) have specific evidence-based protocols and only 7 (16.7%) have a patient satisfaction methodology. In the private scenario there were 56 responses (10 excluded). There is also a concentration in the Southeastern and Southern regions. Thirty-nine centers (84.8%) have access to endoscopic procedures and 19 perform enteroscopy and/or small bowel capsule endoscopy, more than what is observed in the public environment. Infusion therapy is available in 24 centers (52.2%). Thirty-nine centers (84.8%) maintain a specific IBD patient database, 17 (37%) have an IBD nurse, 36 (78.3%) have specific evidence-based protocols, and 22 (47. 8%) apply a patient satisfaction methodology. CONCLUSION: IBD CCU in Brazil were mainly located in the Southeastern and Southern regions of the country. Most centers have dedicated multidisciplinary teams and IBD specialists. There is still a current need to improve the proportion of IBD nurses in IBD care in Brazil. BACKGROUND: â¢In Brazil, there is no validated methodology for evaluating health services recognized as comprehensive care units (CCU), making it difficult to assess the quality of care provided. BACKGROUND: â¢Most CCU were concentrated in the Southeast region and only one (2.4%) in the Northeast region of Brazil. This pattern follows the epidemiological trends of IBD in the country. BACKGROUND: â¢There is still difficulty in accessing enteroscopy and/or small bowel capsule endoscopy in the public health system. BACKGROUND: â¢Most centers have dedicated multidisciplinary teams and IBD specialist doctors. BACKGROUND: â¢There is still a current need to improve the proportion of nurses treating IBD in Brazil.

The incidence and prevalence of inflammatory bowel disease (IBD), namely Crohn's disease and ulcerative colitis, have increased in Latin America over the past few decades. Although incidence is accelerating in some countries in the region, other areas in Latin America are already transitioning into the next epidemiological stage-ie, compounding prevalence-with a similar epidemiological profile to the western world. Consequently, more attention must be given to the diagnosis and management of IBD in Latin America. In this Review, we provide an overview of epidemiology, potential local environmental risk factors, challenges in the management of IBD, and limitations due to the heterogenity of health-care systems, both public and private, in Latin America. Unresolved issues in the region include inadequate access to diagnostic resources, biological therapies, tight disease monitoring (including treat to target therapy, surveillance and prevention of complications, drug monitoring), and specialised IBD surgery. Local guidelines are an important effort to overcome barriers in IBD management. Advancements in long-term health-care policies will be important to promote early diagnosis, access to new treatments, and improvements in research in Latin America. These improvements will not only affect overall health care but will also lead to optimal prioritisation of IBD-related costs and resources and enhance the quality of life of people with IBD in Latin America.

The Brazilian Organization for Crohn's Disease and Colitis (GEDIIB) established a national registry of inflammatory bowel disease (IBD). The aim of the study was to identify clinical factors associated with disease severity in IBD patients in Brazil. A population-based risk model aimed at stratifying the severity of IBD based on previous hospitalization, use of biologics, and need for surgery for ulcerative colitis (UC) and Crohn's Disease (CD) and on previous complications for CD. A total of 1179 patients (34.4 ± 14.7y; females 59%) were included: 46.6% with UC, 44.2% with CD, and 0.9% with unclassified IBD (IBD-U). The time from the beginning of the symptoms to diagnosis was 3.85y. In CD, 41.2% of patients presented with ileocolic disease, 32% inflammatory behavior, and 15.5% perianal disease. In UC, 46.3% presented with extensive colitis. Regarding treatment, 68.1%, 67%, and 47.6% received biological therapy, salicylates and immunosuppressors, respectively. Severe disease was associated with the presence of extensive colitis, EIM, male, comorbidities, and familial history of colorectal cancer in patients with UC. The presence of Montreal B2 and B3 behaviors, colonic location, and EIM were associated with CD severity. In conclusion, disease severity was associated with younger age, greater disease extent, and the presence of rheumatic EIM.

Latin America (LATAM) is a large region comprising 47 countries and territories. Each one carries a different cultural and historical background, diverse political systems, and a particular approach to healthcare management. There is a lack of high-quality data on the epidemiology of inflammatory bowel diseases (IBD) in this region, including broad and detailed information about the penetration of biological and advanced therapies as treatment strategies. From an IBD perspective, patients experience, in general, fragmentations and inequities in the healthcare systems, with different and usually delayed access to qualified health services. This review explores the barriers to accessing IBD care throughout LATAM. The authors compiled data from multiple sources, such as studies focusing on epidemiology, biological penetration, and surgical rates. In addition, overall access to IBD treatments was assessed through a questionnaire distributed to physicians in LATAM via email and direct messaging to capture local perspectives.
RESUMEN
BACKGROUND: Despite optimized medical therapy, contemporary risk of surgery in inflammatory bowel diseases (IBD) after 10 years of diagnosis is 9.2% in patients with ulcerative colitis (UC) and 26.2% in Crohn's disease, (CD) in the biological era. OBJECTIVE: This consensus aims to detail guidance to the most appropriate surgical procedures in different IBD scenarios. In addition, it details surgical indications and perioperative management of adult patients with CD and UC. METHODS: Our consensus was developed by colorectal surgeons and gastroenterologists representing the Brazilian Study Group of Inflammatory Bowel Diseases (GEDIIB), with the Rapid Review methodology being conducted to support the recommendations/statements. Surgical recommendations were structured and mapped according to the disease phenotypes, surgical indications, and techniques. After structuring the recommendations/statements, the modified Delphi Panel methodology was used to conduct the voting by experts in IBD surgery and gastroenterology. This consisted of three rounds: two using a personalized and anonymous online voting platform and one face-to-face presential meeting. Whenever participants did not agree with specific statements or recommendations, an option to outline possible reasons was offered to enable free-text responses and provide the opportunity for the experts to elaborate or explain disagreement. The consensus of recommendations/statements in each round was considered to have been reached if there was ≥80% agreement. RESULTS AND CONCLUSION: This consensus addressed the most relevant information to guide the decision-making process for adequate surgical management of CD and UC. It synthesizes recommendations developed from evidence-based statements and state-of-art knowledge. Surgical recommendations were structured and mapped according to the different disease phenotypes, indications for surgery and perioperative management. Specific focus of our consensus was given to elective and emergency surgical procedures, determining when to indicate surgery and which procedures may be the more appropriate. The consensus is targeted to gastroenterologists and surgeons interested in the treatment and management of adult patients with CD or UC and supports decision-making of healthcare payors, institutional leaders, and/or administrators.

BACKGROUND: Inflammatory bowel diseases are immune-mediated disorders that include Crohn's disease (CD) and ulcerative colitis (UC). UC is a progressive disease that affects the colorectal mucosa causing debilitating symptoms leading to high morbidity and work disability. As a consequence of chronic colonic inflammation, UC is also associated with an increased risk of colorectal cancer. OBJECTIVE: This consensus aims to provide guidance on the most effective medical management of adult patients with UC. METHODS: A consensus statement was developed by stakeholders representing Brazilian gastroenterologists and colorectal surgeons (Brazilian Organization for Crohn's Disease and Colitis [GEDIIB]). A systematic review including the most recent evidence was conducted to support the recommendations and statements. All recommendations/statements were endorsed using a modified Delphi Panel by the stakeholders/experts in inflammatory bowel disease with at least 80% or greater consensus. RESULTS AND CONCLUSION: The medical recommendations (pharmacological and non-pharmacological) were mapped according to the stage of treatment and severity of the disease onto three domains: management and treatment (drug and surgical interventions), criteria for evaluating the effectiveness of medical treatment, and follow-up/patient monitoring after initial treatment. The consensus targeted general practitioners, gastroenterologists and surgeons who manage patients with UC, and supports decision-making processes by health insurance companies, regulatory agencies, health institutional leaders, and administrators.

BACKGROUND: Inflammatory bowel disease (IBD) is an immune-mediated disorder that includes Crohn's disease (CD) and ulcerative colitis. CD is characterized by a transmural intestinal involvement from the mouth to the anus with recurrent and remitting symptoms that can lead to progressive bowel damage and disability over time. OBJECTIVE: To guide the safest and effective medical treatments of adults with CD. METHODS: This consensus was developed by stakeholders representing Brazilian gastroenterologists and colorectal surgeons (Brazilian Organization for Crohn's disease and Colitis (GEDIIB)). A systematic review of the most recent evidence was conducted to support the recommendations/statements. All included recommendations and statements were endorsed in a modified Delphi panel by the stakeholders and experts in IBD with an agreement of at least 80% or greater consensus rate. RESULTS AND CONCLUSION: The medical recommendations (pharmacological and non-pharmacological interventions) were mapped according to the stage of treatment and severity of the disease in three domains: management and treatment (drug and surgical interventions), criteria for evaluating the effectiveness of medical treatment, and follow-up/patient monitoring after initial treatment. The consensus is targeted towards general practitioners, gastroenterologists, and surgeons interested in treating and managing adults with CD and supports the decision-making of health insurance companies, regulatory agencies, and health institutional leaders or administrators.

Background: Population-based data on epidemiology of Inflammatory Bowel Diseases (IBD) in Brazil are scarce. This study aims to define temporal trends of incidence and prevalence rates of Crohn's disease (CD) and ulcerative colitis (UC) in Brazil. Methods: All IBD patients from the public healthcare national system were included from January 2012 to December 2020. Average Annual Percent Change (AAPC) and 95% confidence intervals (CI) were calculated using log-linear regression for incidence and binomial regression for prevalence. Moran's I autocorrelation index was used to analyse clustering of cities by level of prevalence. Findings: A total of 212,026 IBD patients were included. Incidence of IBD rose from 9.4 in 2012 to 9.6 per 100,000 in 2020 (AAPC=0.8%; 95% CI -0.37, 1.99); for UC, incidence increased from 5.7 to 6.9 per 100,000 (AAPC=3.0%; 95% CI 1.51, 4.58) and for CD incidence decreased from 3.7 to 2.7 per 100,000 (AAPC=-3.2%; 95% CI -4.45, -2.02). Prevalence of IBD increased from 30.0 in 2012 to 100.1 per 100,000 in 2020 (AAPC=14.8%; CI 14.78-14.95); for UC, from 15.7 to 56.5 per 100,000 (AAPC=16.0%; CI 15.94, 16.17); for CD from 12.6 to 33.7 per 100,000 (AAPC=12.1% CI 11.95, 12.02). A south-north gradient was observed in 2020 prevalence rates of IBD [I=0.40 (p<0.0001)], CD [I=0.22 (p<0.0001)] and UC [I=0.42 (p<0.0001)]. Interpretation: Incidence of CD is decreasing whereas of UC is increasing, leading to stabilization in the incidence of IBD from 2012 to 2020 in Brazil. Prevalence of IBD has been climbing with 0.1% of Brazilians living with IBD in 2020. Funding: None.
RESUMEN
BACKGROUND: In many patients, the diagnosis of Crohn's disease (CD) is made during surgery for appendicitis in urgent settings. Intraoperative diagnosis can be challenging in certain cases, especially for less experienced surgeons. OBJECTIVE: Review of the literature searching for scientific evidence that can guide surgeons through optimal management of ileocecal CD found incidentally in surgery for acute appendicitis (AA). METHODS: Included studies were identified by electronic search in the PubMed database according to the Preferred Items of Reports for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. The quality and bias assessments were performed by Methodological Index for Non-Randomized Studies (MINORS) criteria for non-randomized studies. RESULTS: A total of 313 studies were initially identified, six of which were selected (all retrospective) for qualitative assessment (two studies were comparative and four only descriptive case series). Four studies identified a high rate of complications when appendectomy or ileocolectomy were performed and in only one, there was no increased risk of postoperative complications with appendectomy. In the sixth study, diarrhea, previous abdominal pain, preoperative anemia and thrombocytopenia were independent predictors for CD in patients previously operated for suspected AA. CONCLUSION: Despite the paucity of data and low quality of evidence, a macroscopically normal appendix should be preserved in the absence of complicated disease when CD is suspected in surgery for AA. Ileocecal resections should be reserved for complicated disease (inflammatory mass, ischemia, perforation or obstruction). Further prospective studies are needed to confirm these claims.

BACKGROUND: With the paradigm shift related to the overspread use of biological agents in the treatment of inflammatory bowel diseases (IBD), several questions emerged from the surgical perspective. Whether the use of biologicals would be associated with higher rates of postoperative complications in ulcerative colitis (UC) patients still remains controversial. AIMS: We aimed to analyze the literature, searching for studies that correlated postoperative complications and preoperative exposure to biologics in UC patients, and synthesize these data qualitatively in order to check the possible impact of biologics on postoperative surgical morbidity in this population. METHODS: Included studies were identified by electronic search in the PUBMED database according to the PRISMA (Preferred Items of Reports for Systematic Reviews and Meta-Analysis) guidelines. The quality and bias assessments were performed by MINORS (methodological index for non-randomized studies) criteria for non-randomized studies. RESULTS: 608 studies were initially identified, 22 of which were selected for qualitative evaluation. From those, 19 studies (17 retrospective and two prospective) included preoperative anti-TNF. Seven described an increased risk of postoperative complications, and 12 showed no significant increase postoperative morbidity. Only three studies included surgical UC patients with previous use of vedolizumab, two retrospective and one prospective, all with no significant correlation between the drug and an increase in postoperative complication rates. CONCLUSIONS: Despite conflicting results, most studies have not shown increased complication rates after abdominal surgical procedures in patients with UC with preoperative exposure to biologics. Further prospective studies are needed to better establish the impact of preoperative biologics and surgical complications in UC.
RESUMEN
BACKGROUND: Coronavirus disease 2019 (COVID-19) pandemic is still evolving globally, and Brazil is currently one of the most affected countries. It is still debated whether patients with inflammatory bowel disease (IBD) are at a higher risk for developing COVID-19 or its complications. AIM: To assess geographical distribution of IBD patients at the highest risk and correlate these data with COVID-19 mortality rates in Brazil. METHODS: The Brazilian IBD Study Group (Grupo de Estudos da Doença Inflamatória Intestinal do Brasil) developed a web-based survey adapted from the British Society of Gastroenterology guidelines. The included categories were demographic data and inquiries related to risk factors for complications from COVID-19. Patients were categorized as highest, moderate or lowest individual risk. The Spearman correlation test was used to identify any association between highest risk and mortality rates for each state of the country. RESULTS: A total of 3568 patients (65.3% females) were included. Most participants were from the southeastern and southern regions of Brazil, and 84.1% were using immunomodulators and/or biologics. Most patients (55.1%) were at moderate risk, 23.4% were at highest risk and 21.5% were at lowest risk of COVID-19 complications. No association between the proportion of IBD patients at highest risk for COVID-19 complications and higher mortality rates was identified in different Brazilian states (r = 0.146, P = 0.467). CONCLUSION: This study indicates a distinct geographical distribution of IBD patients at highest risk for COVID-19 complications in different states of the country, which may reflect contrasting socioeconomic, educational and healthcare aspects. No association between high risk of IBD and COVID-related mortality rates was identified.

Despite significant advances in medical therapy in the management of Crohn's disease (CD), surgery is still required in a significant proportion of patients and constitutes an important tool in treatment algorithms. Recently, more options of biological agents have been made available, and most patients with CD undergoing surgical procedures have been previously exposed to this class of drugs. There is controversy in the literature as to whether anti-tumor necrosis factor (TNF) agents, anti-integrins, or anti-interleukins (ILs) have a direct relationship with increased postoperative complications. In this narrative review, the authors summarize the most important data regarding the effect of biologics on postoperative outcomes in CD. Most studies (with different designs) are based on the experience with anti-TNF agents, mostly with infliximab. Some studies outlined the relationship between vedolizumab and postoperative complications, and there is a lack of data with ustekinumab in this scenario. Most studies are retrospective, but few prospective data are available. A cause-effect (proof of concept) direct relationship between biologics and an increase in postoperative morbidity has not been demonstrated to date. Several confounding factors such as previous use of steroids, malnutrition, and unfavorable abdominal conditions have a definitely effect on postoperative complications in CD. Biologics seem safe to be used in the perioperative period, but available data are still controversial. Multidisciplinary individualized decisions should be made on a case-to-case basis, adapting the surgical strategy according to risk factors involved.
RESUMEN
BACKGROUND: Inflammatory bowel diseases (IBD) are chronic inflammatory affections of recurrent nature whose incidence and prevalence rates have increased, including in Brazil. In long term, they are responsible for structural damage that impacts quality of life, morbidity and mortality of patients. OBJECTIVE: To describe the profile of physicians who treat IBD patients as well as the characteristics of IBD care, unmet demands and difficulties. METHODS: A questionnaire containing 17 items was prepared and sent to 286 physicians from 101 Brazilian cities across 21 states and the Federal District, selected from the register of the State Commission of the "Study Group of Inflammatory Bowel Disease of Brazil" (GEDIIB). RESULTS: The majority of the physicians who answered the questionnaire were gastroenterologists and colorectal surgeons. More than 60% had up to 20 years of experience in the specialty and 53.14% worked at three or more locations. Difficulties in accessing or releasing medicines were evident in this questionnaire, as was referrals to allied healthy professionals working in IBD-related fields. More than 75% of physicians reported difficulties in performing double-balloon enteroscopy and capsule endoscopy, and 67.8% reported difficulties in measuring calprotectin. With regard to the number of patients seen by each physician, it was shown that patients do not concentrate under the responsibility of few doctors. Infliximab and adalimumab were the most commonly used biological medicines and there was a higher prescription of 5-ASA derivatives for ulcerative colitis than for Crohn's disease. Steroids were prescribed to a smaller proportion of patients in both diseases. The topics "biological therapy failure" and "new drugs" were reported as those with higher priority for discussion in medical congresses. In relation to possible differences among the country's regions, physicians from the North region reported greater difficulty in accessing complementary exams while those from the Northeast region indicated greater difficulty in accessing or releasing medicines. CONCLUSION: The data obtained through this study demonstrate the profile of specialized medical care in IBD and are a useful tool for the implementation of government policies and for the Brazilian society as a whole.

BACKGROUND: The introduction of anti-TNF agents represented a landmark in the management of both Crohn's disease (CD) and ulcerative colitis (UC), with improved efficacy and safety when compared with conventional treatment. However, significant challenges still exist in Latin America to facilitate the access of biological agents for physicians and patients. OBJECTIVE: The aim of this review was to summarize current evidence on penetration of biological agents for CD and UC in Latin America. METHODS: Data are derived from a previous complete systematic review that explored different characteristics of inflammatory bowel diseases (IBD) in Latin America. The studies fully included in this previous systematic review which contained detailed descriptions of the percentage of use of biological agents in different cohorts throughout Latin American and Caribbean countries were included, and descriptive findings were compiled, describing CD and UC penetration of these drugs in different patient cohorts from different countries. RESULTS: From the 61 studies included in the original systematic review, only 19 included data of the percentage of patients treated with biological agents. Anti-TNF use in CD varied from 1.51% in Mexico up to 46.9% in Colombia, with most of the studies describing anti-TNF use in approximately 20%-40% of CD patients. On the other side, the frequency of the use of biologics was clearly lower in UC, varying from 0% in 2009 to up 16.2% in 2018, according to two different Mexican studies. Only two studies described the penetration of anti-TNF agents in IBD overall: 13.4% in a Colombian and 37.93% in a Brazilian study. No studies described percentage of use of new biologic agents (vedolizumab and ustekinumab). CONCLUSION: Penetration of anti-TNF agents in Latin America is comparable to the rest of the world in CD, but lower in UC. With the increase in the incidence and prevalence of IBD, specific strategies to increase access to anti-TNF agents in UC and new biological agents overall are warranted.

ABSTRACT Background: The most efficient way to prevent complications from inflammatory bowel disease (IBD) is to provide patients with optimized care. Nonetheless, in Brazil, there is no validated methodology for evaluating health services recognized as comprehensive care units (CCU), making it difficult to assess the quality of care provided. Objective: To understand the current scenario, map the distribution of centers and identify strengths and weaknesses, considering local and regional characteristics. Methods: The study was carried out in three phases. Initially, the Brazilian Organization for Crohn's disease and colitis (GEDIIB) developed 22 questions to characterize CCU in Brazil. In the second phase, all GEDIIB members were invited to respond to the survey with the 11 questions considered most relevant. In the last phase, an interim analysis of the results was performed, using the IBM SPSS Statistics v 29.0.1.0 software. Descriptive statistics were used to characterize the center's profile. The chi-square test was used to compare categorical variables. Results: There were 53 responses from public centers (11 excluded). Most centers were concentrated in the Southeastern (n=22/52.4%) and only 1 (2.4%) in the Northern region of Brazil. Thirty-nine centers (92.9%) perform endoscopic procedures, but only 9 (21.4%) have access to enteroscopy and/or small bowel capsule endoscopy. Thirty-three centers (78.6%) offer infusion therapy locally, 26 (61.9%) maintain IBD patient records, 13 (31.0%) reported having an IBD nurse, 34 (81.0%) have specific evidence-based protocols and only 7 (16.7%) have a patient satisfaction methodology. In the private scenario there were 56 responses (10 excluded). There is also a concentration in the Southeastern and Southern regions. Thirty-nine centers (84.8%) have access to endoscopic procedures and 19 perform enteroscopy and/or small bowel capsule endoscopy, more than what is observed in the public environment. Infusion therapy is available in 24 centers (52.2%). Thirty-nine centers (84.8%) maintain a specific IBD patient database, 17 (37%) have an IBD nurse, 36 (78.3%) have specific evidence-based protocols, and 22 (47. 8%) apply a patient satisfaction methodology. Conclusion: IBD CCU in Brazil were mainly located in the Southeastern and Southern regions of the country. Most centers have dedicated multidisciplinary teams and IBD specialists. There is still a current need to improve the proportion of IBD nurses in IBD care in Brazil.
RESUMO Contexto: A forma mais eficiente de prevenir complicações da doença inflamatória intestinal (DII) é proporcionar aos pacientes cuidados otimizados. Contudo, no Brasil não existe uma metodologia validada para avaliação de serviços de saúde reconhecidos como unidades de atenção integral (UAI), dificultando a avaliação da qualidade da assistência prestada. Objetivo: Compreender o cenário atual, mapear a distribuição dos polos e identificar pontos fortes e fracos, considerando as características locais e regionais. Métodos: O estudo foi realizado em três fases. Inicialmente, a Organização Brasileira para Doença de Crohn e Colite (GEDIIB) desenvolveu 22 questões para caracterizar as UAI no Brasil. Na segunda fase, todos os membros do GEDIIB foram convidados a responder ao inquérito com as 11 questões consideradas mais relevantes. Na última fase foi realizada uma análise dos resultados, utilizando o software IBM SPSS Statistics v 29.0.1.0. Estatísticas descritivas foram utilizadas para caracterizar o perfil do centro. O teste qui-quadrado foi utilizado para comparar variáveis categóricas. Resultados: Houve 53 respostas de centros públicos (11 excluídas). A maioria das UAI concentrou-se na região sudeste (n=22/52,4%) e apenas 1 (2,4%) na região norte do Brasil. Trinta e nove centros (92,9%) realizam procedimentos endoscópicos, mas apenas 9 (21,4%) têm acesso à enteroscopia e/ou cápsula endoscópica. Trinta e três centros (78,6%) oferecem terapia de infusão localmente, 26 (61,9%) mantêm registros de pacientes com DII, 13 (31,0%) relataram ter uma enfermeira para DII, 34 (81,0%) têm protocolos específicos baseados em evidências e apenas 7 (16,7%) %) possuem uma metodologia de satisfação do paciente. No cenário privado houve 56 respostas (10 excluídas). Há também concentração nas regiões sudeste e sul. Trinta e nove centros (84,8%) têm acesso a procedimentos endoscópicos e 19 realizam enteroscopia e/ou cápsula endoscópica, mais do que o observado no ambiente público. A terapia infusional está disponível em 24 centros (52,2%). Trinta e nove centros (84,8%) mantêm um banco de dados específico de pacientes com DII, 17 (37%) têm uma enfermeira para DII, 36 (78,3%) têm protocolos específicos baseados em evidências e 22 (47,8%) aplicam uma metodologia de satisfação do paciente. Conclusão: As UAI do DII no Brasil estavam localizadas principalmente nas regiões sudeste e sul do país. A maioria dos centros possui equipes multidisciplinares dedicadas e médicos com experiencia em DII. Ainda há uma necessidade atual de melhorar a proporção de enfermeiros no tratamento de DII no Brasil.
RESUMEN
PURPOSE: To observe the histological alterations in the liver and biochemistry in the blood that can happen in Wistar rat, after the ligature of right hepatic duct. METHODS: In this study were used rats (n=46) of Wistar pedigree. The animal groups (n=46) were distributed in 6 experimented sub-groups (n=6). It was held a ligature surgery of the right hepatic duct and euthanasia in 7, 14, 21, 28, 60 and 90 days and the biochemistry control group (n=10), that animals had 2ml of their blood taken by cardiac puncture for biochemistry study with value analyses of bilirubins, transaminasis, lactic desidrogenasis, alkaline phophatase and gamma-glutamil-transferase. Given the expected time of each group, the animals were submitted to anesthesia procedure and cavity re-opening, being held intra-cardiac puncture and with 2ml blood collected for biochemistry analyses. It was proceeded the liver resection, being the liver put in formol solution to 10% for a period of 24 hours and taken to the histology. RESULTS: It was not possible to identify results that express significant differences as the existence of alterations histological and biochemical between the different groups. CONCLUSION: At the end of the study, it was not possible to identify histological and biochemical alterations that express significant differences between livers of the animals from the right linked hepatic duct and the animals of the control group.
